WM 6 W17 United States Patent ROLLER VIBRATING DEVICE Samuel L. McNair, 733 Bedford St., Whitman, Mass. Filed Aug. 7, 1957, Ser. No. 676,849

3 Claims. (Cl. 128-57) This invention relates to a roller vibrating device, particularly for use in massaging different parts of the body.

One object of my invention is to provide a roller vibrating device so constructed that its parts can be manufactured and assembled at a relatively low cost.

Another object is to provide a support or mounting for a roller member so constructed that it can be directly attached to a clapper so that the maximum vibration can be transmitted to the roller member.

A further object is to construct said device that it can provide unusually effective vibrations considering its relatively low cost.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and 0p erative arrangement of parts such as is disclosed by the drawing. The nature of the invention is such as to render it susceptible to various changes and modifications, and therefore, I am not to be limited to the construction disclosed by the drawing, nor to the particular parts described in the specification; but am entitled to ail such changes therefrom as fall within the scope of my claims.

In the drawing:

Fig. 1 is a top plan view of my roller vibrating dev1ce.

Fig. 2 is a side elevational view thereof.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2.

Fig. Fig. 1.

Fig. 5 is a wiring diagram showing the electrical circuit used in my device.

As illustrated, my roller massaging device has a main support shown as a U-shaped base the bottom of which has bosses 12 which receive brass inserts 14 in which are screw-threaded holes 16. A cover 18 is held to said base 10 by screws 17, and said cover has holes in opposite sides 18a to fixedly receive left and right shafts 19 and 20 respectively upon which are mounted handles 34 and 36 respectively which are later described. Said cover 18 has a large openingZl at the top, later referred to.

Attached to said base 10 by screws 22 is a well-known electro-magnetic motor M to which is attached a leg 23 of a vibrant armature shown as a U-shaped clapper, the other leg 23:: of which is spaced from said motor, and attached, as by welding, to the intermediate or connecting portion 24 of a mounting which has two sides 26 at opposite ends of said connecting portion 24. These sides 26 extend at a right angle to said connecting portion 24, each having a recess or dimple 28 therein to rotatably receive supporting pins or pintles 32 which fixedly extend into the two opposite ends to form part of a roller member 30. This roller may be made of wood, plastic or the like, and it rotates freely with'its said pintles 32. I

For convenience, a left handle 34 is provided which 4 is a sectional view taken on the line 4-4 of on said shaft 20, having an elongate hole 38 therethrough. A bushing 40 it set in said cover 18 in communication with said opening 38.

Said base 10 has another boss 44 which receives a screw-threaded insert 45 in which a selenium rectifier 46 is mounted by a screw 48 that extends into said insert 45 and screw-threadedly connects therewith. This recmay be integral. Also a right handle 36 is mounted tifier 46 may be included in the electrical circuit, when desired, to intensify the vibrations.

A cord 50, enclosing electric wires, extends through said handle hole 38 and bushing 40, being adapted to connect with a source of electrical supply not shown.

A wiring diagram is shown in said Fig. 5. Electrical current passing through a wire 51 continues to a switch 52, having a contact arm 53. When the latter contacts said LO contact member 54, an electrical circuit is completed by wires 55 and 56 through said motor M, and through wire 57 as shown, to thereby operate the motor and vibrate said clapper. When said contact arm 53 contacts the Hi contact member 59, said rectifier 46 is included in the circuit by means of wire 60 extending to it from said contact member 59. Another wire 62 extends from the rectifier through said wire 56 to said motor M.

When said motor M is operated, said clapper 23 vibrates said roller 30 through said mounting. Since said 'pintles 32 are rotatably mounted in said dimples 40 said roller, being fixed to said pintles, may be manually rotated when desired by rolling contact with any part of the body.

What I claim is:

1. A roller vibrating device comprising a base, a cover connected to said base embodying two sides, and having an opening therein, said sides having two handles connected to, and extending laterally beyond, said two sides, a motor supported by said base, a vibrant armature connected to said motor, a mounting embodying an intermediate portion attached to said armature and ermbodying two sides directly opposite said cover sides, and a roller mounted on said mounting sides and extending into said opening. 7

2. A roller vibrating device comprising a base, an outer cover connected to said base embodying two sides and having an opening therein, a motor supported by said base, a vibrant armature connected to, and a portion of which is spaced from, said motor, a U-shaped mounting embodying an intermediate portion attached to said armature spaced portion and embodying two sides directly opposite said cover sides, supporting means mounted insaid mounting sides, and a roller rotatably mounted on said supporting means and extending into said opening.

3. A roller vibrating device comprising a base, a cover connected to said base embodying two sides and having an opening therein, a motor supported by said base, a vibrant armature connected to, and a portion of which is spaced from, said motor, a U-shaped mounting attached to said armature spaced portion and embodying two sides directly opposite said cover sides, supporting means mounted in said mounting sides, a roller rotatably mounted on said supporting means and extending into said opening, and two handles connected to and extending laterally beyond said two cover sides and extending lower than said roller and later-ally opposite said motor.
